The separator outlet temperature and main steam pressure are two essential controlled parameters within CCS.Their values set directly influence the safe and economical operation of the power plant.However,the impact of these set values on the energy consumption of secondary reheat power plants remains unclear.To elucidate their effects on the energy consumption characteristics during flexible operation,this paper employs the Apros software to establish a dynamic model of a secondary reheat power plant,which is then validated against actual operational data to ensure its accuracy.By manipulating the separator outlet temperature and main steam pressure,the influences of these parameters on the energy consumption characteristics of the secondary reheat power plant are revealed.Simulation results indicate that variations in the separator outlet temperature have an insignificant impact on energy consumption.With an increase in separator outlet temperature,the reduced superheater heat absorption efficiency leads to a higher coal consumption for power generation.Conversely,changes in main steam pressure exhibit a more significant impact on energy consumption.
